Plays previously had been relayed through quarterbacks coach Wade Wilson, who now will move up to the coaching booth to aid Callahan in reading defensive coverages, according to Werder.

The change in duties is interesting in that it would, conceivably, allow Garrett to trump Callahan's play calls. It also puts more on Garrett's plate. He must now manage the game while still making sure his quarterback gets the play with plenty of time to make checks at the line.
